I need to delete a thread but there is no option to!

It's urgent too and I don't know why I can't because I am registered and logged in! And I wrote to whoever runs the site but the thread is still up! I would delete my account but I don't know if that would help and there is no option to do that either! And I don't want to lose my friend over a stupid mistake! :'( please help!
